What are some signs of blood poisoning?

Signs of blood poisoning include rapid breathing, fever, chills and increased heart rate, states Healthline. In severe cases, patients may experience shock, confusion, red spots on the skin and reduced urine production.

Blood poisoning refers to bacteria in the blood, not actual poisoning, explains Mayo Clinic. It is more prevalent in people with severe wounds, dental extractions and those recovering from surgeries, reports Healthline. Older people, young children and people with weak immune systems are also at higher risk for blood poisoning.

Blood poisoning requires immediate treatment to prevent bacteria from spreading to other parts of the body, such as heart valves, advises Mayo Clinic.
